Polio, also known as poliomyelitis, is an acute infectious disease caused by poliovirus infections I, II and III, mostly in infants and young children, and has been described by the medical community as "the biggest killer threatening the lives and health of children".
prevention and control work in China began in the 1960s, through the national promotion of oral polio detoxifying live vaccine, commonly known as "sugar pills", effectively control the occurrence of the disease. Oral polio-reducing live vaccine is a type of vaccine included in the national immunization programme because of its good immune effect and low price. However, due to its detoxifying live vaccine, there is still a potential risk of disease. Imported polio inactivated vaccine imported from abroad has been listed in China, but the purchase price is very high.
January 14, 2015, the State Food and Drug Administration approved the world's first production registration application for the Sabin strain of polio inactivated vaccine (single seedling). The vaccine, developed by the Institute of Medical Biology of the Chinese Academy of Medical Sciences, is mainly used by injection to prevent poliovirus infection in children, not only improving the safety of vaccination, but also breaking the monopoly of developed countries on the production of polio inactivated vaccines.
it is understood that the vaccine will be gradually integrated into our planned immunization program. The World Health Organization has also recently sent a letter to the relevant departments of our country proposing the introduction of the Sabin polio inactivated vaccine produced in our country into the Global Polio Eradication Action Plan.
